Convertible two-dimensional-three-dimensional display using an LED array based on modified integral imaging.

We propose a two-dimensional (2D) to three-dimensional (3D) convertible display technique using a light-emitting diode (LED) array based on the principle of modified integral imaging. This system can be electrically converted between 3D and 2D modes by using different combinations of LEDs in the LED array without any mechanical movement. The LED array, which is controlled electrically, is used for backlight, and a lens array is used for making a point light source array with higher density. We explain the principle of operation and present experimental results.

Depth-enhanced three-dimensional integral imaging by use of multilayered display devices.

Integral imaging is one of the promising three-dimensional display techniques and has many advantages. However, one disadvantage of integral imaging is the limited image depth. The image can be displayed only around the central depth plane. We propose a depth-enhanced integral imaging using multilayered display devices. We locate transparent display devices that use liquid crystal in parallel to each other and incorporate them into an integral imaging system. As a result, the proposed method has multiple central depth planes and permits the limitation of expressible depth to be overcome. The principle of the proposed method is explained, and some experimental results are presented.
